hai sir..i already done all the connection and it works perfectly and knows I'm facing a new problem which is when I want to add a new fingerprint through the webpage I cannot add it, plus the screen on OLED doesn't display the scanning part such as on your video at minute 6 may I know how can I solve this problem? thank you, sir.
Can I use arduino behalf of node MCU & in which line of code I will have to rectify for that...Thanks in advance you are doing great job keep making such amazing videos 👍
can you adding a person picture to this project. i mean, after a person done thumbprint the data will show approved. at the same time the data will show our pictures.

Hi, I have two fingerprint modules. The r307 fingerprint module says it's found but the led light won't light up or do anything else. The other one, a DY 50. The led lights up but it won't find the fingerprint sensor. Help me please. :(
I think r307 is working fine, if your serial monitor is showing the sensor work then it should work, coming to the led it glow on certain condition only(sensing a finger print), may the the special condition is not satisfying to glow led. or the led may damaged. you don't have to worry about that led is just a indication to let you know the certain action is happening with sensor, try again to register and validate the finger prints. then let me know if you have any issues???
Coming to DY50, May be the TX and Rx pins are reversely connected or not properly connected. so verify the hardware connections and let me know if any issues....
sir my attendance is not being marked, its registering student finger print id but not marking attendance what could be the possible mistake we are doing please help me
I want to add a ethernet port with this setup to get connection through wire. can i add ethernet to this setup? if yes how can i add? is there anything should i change in the code for add ethernet. Wifi is not stable thats why im looking for a ethernet option. and also i have multiple wifi connections if one connection fail i can use other. is there any option to add multiple wifi connection to the nodemcu by changing the code?????
HELP ME....!!!! I'm facing a very annoying issue here.... whenever I'm trying to enroll a fingerprint through database (e.g 6:15 in the video) , my fingerprint sensor is supposed to blink continuously for scanning a fingerprint as we see in the video... BUT, my fingerprint sensor is not responding correctly at all.. rather it blinks about 11s periodically without enrolling the fingerprint... (I've checked running fingerprint enrollment code from arduino example....In that code the sensor works fine... it blinks continuously for scanning...But in this code the sensor is not blinking as it should be....)

how to register new employee or student after real implementation is completed (registration is required connecting the device with the computer by USB cable or not)
@@electronicsinnovation ok thanks, i have one other question that is consider you use the node MCU for your project unfortunatly you want to use that Nod MCU for other project it is posible or not (it is posible to use one nod MCU board for different projects)
The Storage capacity Fingerprint sensor is up to 150 unique fingerprints, You can increase up to 150 only. But I have developed a program for 127 Fingerprints prints only, If you wish to increase up to150 you can do it by simply edit the code.
@@electronicsinnovation isn't it possible to store the fingerprint in an external database and store a lot more than that? 150 is just too small. There has to be a way.
That means you have added I'd but you didn't give fingerprint. Kindly give you your fingerprint for two times then you can add another Person. Every time you add I'd and link with finger print and add another. untill and unless you didn't link with finger print it will not move further.
@@electronicsinnovation fingerprint doesn't scan for any id and also newly added user name and data do not add up to the user manager section.how to solve this issie ?
